I had some time to play with Silverlight 2. I like editing Silverlight XAML by hand (in Visual Studio that is the only possiblility), but to get a nice design or add some effects, Expression Blend is helpful. I’m a bit disappointed that there is no SVG support in any of the Microsoft tools – so you cannot easily integrate existing SVG graphics or icons (e.g. from Open Clip Art Library). The free tool Inkscape can help here.
The first outcome of my coding is here (click on the items to edit them; drag the items to change the order).
